Title: 0.06 M Oxalic Acid Skin Contact Danger
Post by: orgrinda on September 05, 2019, 07:30:13 AM

My friend was conducting an experiment with 0.06 M of oxalic acid and at most 10 ml of it dropped on his skin. He did not wash it. Is this hazardous now?

Nope. At these amounts/concentrations oxalic acid on the skin is mainly a mild irritant. If nothing happened immediately I wouldn't care by now.

Not that it was a wise idea to not wash it, just with water.

I used to handle pure oxalic acid on a daily basis during my PhD. Not with my hands but sometimes would come in contact with my skin. Couple years later and my kidneys still work.

Compare this concentration to that in rhubarb leaves
